I ordered from Burnt Ridge...they had a decent selection.

Edible Landscaping also carries quite a few.

After reading a previous post on kolomitkas I ordered from One Green World. My order arrived with healthy, potted plants in superb packaging.

I found their search engine did not help me find which were arctic and which were hardy so I had to call and they were very helpful. I ordered Pasha, September Sun, and Viktor. If I manage to get these going I'll order more next year.

Thanks Mile, I think they may have been my original source. I have one excellent variety, though, that I think was called something like Rossana. It looks like the one they call Hardy Red.

Harvestman, they do have Rossana. It is on the second page of their kiwi section.
